UHVCTM Ultra High Vacuum Cryo Transfer Module - LN2-cooled UHV Suitcase Configuration


Equipped with a liquid nitrogen dewar for active sample cooling, thermal shields (CTD50SHIELDS) enshrouding the sample, as well as a temperature measuring kit, the Ultra High Vacuum Cryo Transfer Module (UHVCTM) enables transport of sensitive samples at cryogenic temperatures under true UHV conditions (E-11mbar). The UHVCTM is, especially compact, lightweight, robust and easy to use.

The sample is situated within a customized cryo shield inside the suitcase in order to be protected from contamination coming off the chamber walls while the suitcase is cold. Integrated viewports in the shields allow for observation of the sample inside.

For easy transfer of samples into your system, the cryo suitcase can either be mounted directly to your loadlock or via our Fast Pump Down Dock. Docking solutions for a variety of analytical and preparation instruments are readily available. Please contact us to discuss your requirements for instrument adaptations.

The high voltage for the ion-pump element is delivered by the rechargeable, battery-driven power supply LSA3.0. The vacuum level is shown directly on the display optimized for SAES™ NexTorr pumps of the types D100-5, D200-5. For activation of the NEG element we provide the designated NEG controller LSN1 .Together with the respective cabling, the temperature can be measured by the LSA3.

To see if this configuration suits your needs, please download our questionnaire for further information.

Don't hesitate to contact us at for more information and the adaptation to your system.
